The first phase of Hudson Yards is slated for completion in the next four years. The complex, which will sit between 10th and 12th Avenues and run from 30th to 34th Street, will include public parks, office towers, shops, restaurants, and more.

It will be made accessible by an extension of the existing No. 7 subway line.

We recently got a tour of the construction site and renderings of what Hudson Yards will look like when it's complete. Keep reading to see what the future holds for Manhattan's West Side.

Located on the far west side of Manhattan, Hudson Yards is one of the biggest private developments in U.S. history. The 28-acre complex will sit above rail tracks that service New York City and is expected to revitalize an entire neighborhood.

The development is just one aspect of a major overhaul of Manhattan's West Side. In the past few years, luxury condos have sprung up alongside the High Line, the Jacob Javits center has been renovated, and the No. 7 subway line is being extended to 11th Avenue to accommodate the area's residents and tourists.

The first phase of Hudson Yards is the Eastern Rail Yard, which will have several residential and office towers, along with dozens of shops and restaurants to occupy an expected 65,000 visitors a day. The Western Yard will be mostly residential.

Construction has been underway since 2012. The developers are working on building two giant platforms that will elevate the skyscrapers above 30 active Long Island Rail Road tracks.

There are five main skyscrapers planned for the Eastern Rail Yard. The first is 10 Hudson Yards, which will rise 895 feet above 30th Street and 10th Avenue, and have 1.7 million square feet of space. Coach, L'Oreal, Fairway, and SAP will be future tenants.

Thirty Hudson Yards will be built on 33rd Street and 10th Avenue. At 1,227 feet tall, it will have 2.6 million square feet of space. Future tenants will be Time Warner, HBO, CNN, and WB, and it's slated for completion in late 2018.

At 1,100 feet in the air, views from the observation deck will be spectacular. The developers sent a drone into the air to create this image of how the landscape will look to visitors.

Connecting the two skyscrapers will be a 1 million-square-foot space for shops and restaurants. It will have seven levels of retail and dining. By 2018, the building will have 20 restaurants, 100 shops, and an anchor department store.

Across the street, between 33rd and 34th Streets, is 55 Hudson Yards. The LEED Gold-certified building will stand 780 feet tall by 2017.

But what most New Yorkers will be particularly excited about is the No. 7 train expansion, which will connect the east side and Queens to Hudson Yards, the High Line, and more. It will serve 40,000 people a day.

The top of the High Line, a popular pedestrian park constructed on a defunct railroad spur, will be accessible from Hudson Yards through a 60-foot public passageway.

The High Line will continue to rope around Hudson Yards, but visitors will also be able to enter the Eastern Rail Yard's public plaza. Eventually, they will be able to seamlessly walk from the No. 7 train to the High Line without taking any stairs or escalators.

Right now, the area is pretty desolate, but it will soon be filled with trees, walking paths, and grassy spaces.

Hudson Yards will also be home to something called "The Culture Shed," a multipurposed venue with seven levels of galleries and performance spaces. It has a moving outer layer that lets it nearly double in size and will host touring art exhibits, New York Fashion Week, and various shows.
